I've just read a part of a long discussion on power supplies by some distinguished members of this forum, and the conclusion is that best power supplies are NOT built on separate boards, but comprise of putting the capacitors as close to the ICs or transistors as possible, calculating trace R and L, paralleling the right value caps etc...

A long read, but they actually quantified the reasons why their amps sound better, and some of which coincide with the FE version optimizations. I'll get back to reading now...

Was able to test the amp today, I got 45Watts into 4 ohms resistive dummy load using 8Amps 24-0-24VAC transformer. (Single channel driven)

As for the sound, It has a wide soundstage and superb detail, the instruments sounded lively.
I compared it to my LM3875, this one has more detail and the bass has more punch. The LM3875 is much softer/smoother though.

For me the sound character is much like BAKSA 50 but with more refinement, more details and more accurate bass.

I'm new to Chip amps. I'm going to build a simple version first to see how it goes. But it's interesting to read about other designs. This design appears to use the LM3886 as a current driver and another opamp for the voltage gain.

So when listening to this amplifier I assume that it is the LM318 that 'sets the tone' for the sound and not the LM3886 ?
